Abstract In situ zooplankton grazing rates on natural particle assemblages were stimated by measuring zooplankton uptake of labelled autotrophic (with Na14CO3) and heterotrophic (with [methyl-3H]-thymidine) particulate matter in 1-h incubations in clear, Plexiglas, Haney chambers. The in situ grazing rates are in the same range as those measured for zooplankton in the laboratory using standard particle counting techniques. A negative selection coefficient for 3H-labelled particles indicated a lower filtration efficiency or avoidance of these particles by zooplankton.
